Grantebru

Grantebru was a Viking city-state in England which existed from 878 to 916, centered around the city of Grantebru (Cambridge). Its Anglo-Saxon name, "Grantebrycge", referred to its location along the River Granta (now the River Cam, hence "Cambridge"). The town grew rapidly due to Norse trade, and the town expanded to the right bank of the Cam. It was reclaimed by Wessex by 916.
